It s often used for storage tanks heat exchangers garage doors and general sheet metal work.

While properties such as superb resistance to corrosion and excellent thermal conductivity are very useful in many applications it is the flexibility and adaptability of aluminum s mechanical properties that make it such a widely used metal. Aluminum is known for its versatility. Corrosion resistant 3003 aluminum sheets and bars. 2m 30s we usually think of rust as the orange brown flakes that form on an exposed steel surface when iron molecules in the metal react with oxygen in the presence of water to produce iron oxides.

It offers a good combination of strength formability and weldability. Galvanized steel screws however are plated with a corrosion resistant coating usually consisting of zinc that is not nearly as reactive with aluminum. Aluminum corrosion resistance is also often only high in a restricted range of ph. The corrosion resistance of this grade is relatively low.

The zinc plating prevents the underlying steel from coming into contact with the aluminum and the risk of corrosion of the aluminum is reduced significantly. Generally speaking aluminum and its alloys have excellent resistance to corrosion. How corrosion resistant is aluminum. 3003 aluminum sheet has a smooth semi shiny finish and is popular for many applications including.
